APAPATUS FOR PREVENTING FROM BEING CHOKEN OF PUNCHING NETTING IN WASTE SCREEN}

The present invention relates to a blockage preventing device of the perforated network of the waste sorter, and in particular, the waste sorter sorts out various mixed wastes such as soil, concrete, rebar, wood, rock, synthetic resin, paper, and other wastes generated at the landfill site. It is to prevent the perforated network from being blocked by wastes containing moisture in the process of treatment to increase the sorting efficiency of wastes.

In general, waste buried in landfills is a mixture of soil, concrete, rebar, wood, vinyl, paper, synthetic resin, and other wastes.

Wastes mixed and buried in this way may cause environmental pollution such as groundwater contamination, but recyclable wastes are also buried together. And because residents oppose the attraction of waste landfills due to environmental pollution, it is difficult to find waste landfills anymore.

The proposed proposal is to dig up the waste from the landfill and sort it out into soil, concrete, rock, vinyl, synthetic resin, paper, and other wastes. Buried landfills have somewhat eliminated scarce landfills.

The waste sorting device was proposed, and the proposed waste sorting device is a hopper for introducing waste and a centrifuge for sorting soil mixed in the waste, and a relatively light waste such as concrete, rock, rebar, wood, Powerful blower is provided to separate waste such as synthetic resin, vinyl, paper, etc.

In addition, a waste transfer conveyor is provided between the hopper and the centrifuge, a first soil transfer conveyor is installed below the centrifuge, and a second soil transfer conveyor is installed at an inlet side of the first soil transfer conveyor at a right angle. A thick waste conveying conveyor is installed at the bottom of the centrifuge outlet side, and a powerful blower is installed under the thick waste conveying conveyor so as to separate and transport the waste by blowing strong wind.

However, when using the waste sorting device equipped with such a centrifuge to sort out the construction waste containing water and soil, the efficiency of the waste sorting operation is lowered due to the blockage of the perforated network of the centrifuge by wet soil. There was a problem.

In order to solve this problem, the "Waste sorting device" of Korean Utility Model Registration No. 255270 (Nov. 12, 2001) was proposed, and the proposed waste sorting device installs a vibrator at the bottom of the vibrating hopper, Four eccentric weights formed by mutual threads are mounted to vibrate by a motor, and a tilt angle controller is installed on the lower frame of the vibration hopper, and a protruding bracket is installed at regular intervals on the outer periphery of the centrifuge formed by a rubber perforated network. The frame of the separator consisted of a rubber roller connected to a shaft with a brush, and a belt conveyor mounted to the bottom of the centrifuge to detach the soil attached to the perforated network by the brush and the rubber roller. Due to the complicated structure, there is a problem that the manufacturing cost is increased, Standing not be placed outside the side one place because a lot of production costs by a landslide drilled only one side of the brush part is installed, there is not no drill a well site blocked problem.

The present invention was devised to solve such a problem. In the process of sorting landfill waste mixed with various types such as soil, concrete, rebar, rock, wood, synthetic resin, paper, and other wastes using a waste sorting machine, The purpose of the present invention is to provide a device for preventing clogging of a perforated network of a waste sorter, which can prevent the perforated network from being blocked by earth and sand, which can increase waste sorting efficiency.

The present invention for achieving the above object is to rotate at least one roll brush having a plurality of brushes formed on the outer surface of the hollow member to the support shaft formed on the inlet and outlet sides of the centrifuge to contact the inner wall of the inner perforated network The object is achieved by providing an apparatus for preventing clogging of a perforated network of a waste sorter, characterized in that it is possibly fixed.
